27 Claims.

My present'invention relates primarily to cen-V tral chassis lubrication oi automobiles and whilev objects of the invention toeffect lubricanti pro- 10 pulsion to the chassis bearings by av simple arrangement from power already available on the vehicle for other purposes, particularly'the suction at the intake manifold, without need of com- Y plicat-ion by auxiliaryaccumulators or trip .mechanisms, without resort to reduction gearing or other mechanical operating or wearing connection with the running mechanism ofthe vehicle and without manualactuation orcontrol; and also to meter the lubricant to the bearings in ac# cordance with the requirements of each bearing throughout the operation of the vehicle with assurance oi adequate lubrication on the one hand under steady or favorable trafc conditions and Without excessive. feed of lubricant on the other hand under .unfavorable or'spasmodically varying trame. conditions.

In common with the invention of said applica tion, the present invention makes use of a lubricant pump of small volume, preferably a reciprocating plunger pump submerged Ain a supply of lubricant and actuated by a pulsating motor operated by the differential pressure between atmospheric and a source oi varying uid pressure, such as the suction at the intake manifold. The motor may consist oi an encased diaphragm with a xed rim and centralk stiffened portion subjected to said differential pressure andmoved thereby against the resilient opposition preferably of a spring. `The spring may be coiled about the rod through which .the diaphragm is connected to the pump plunger and it may balance the diaphragm in a position corresponding to the magnitude of said differential pressure. The diaphragm may have sufcient slack or looseness between its fixed rim and its central stiened movable portion, as, to admit of very ready displacement ofthe latter, any substantial increase in suction during operation, as byv throttle closing, elevating thel diaphragm and charging the pump and-any decrease in suction as by opening the throttle, enabling the stressed spring to lowe it and to effect discharge oi the pump.

An installation of the above type if properly adapted to average automobile operating conditions may overlubricate under conditions oi' dense by the use of a highly restricted passage or choke urban traiilc where the throttle is opened and closed at frequent intervals. To obviate overlubrication underjsuch conditions without at the same time impairing proper lubrication underV other running conditions, it is-desirable todamp, k5 retard,reduce or chokek theeffect of frequent violent pulsations of suction incurred under such conditions of driving. This may be accomplished asv disclosed in the vabove identied application l0 in the course of fluid flow between the intake manifold and the diaphragm. In the present application I have in addition disclosed a flow governor for precluding overlubrication, adapted to be positioned in the course of lubricant feedr from l5 Vthe plunger pumptothe. distributing line. f

Figs. 1,' 2 and 3 show the reservoir, pump and motor'combination, the pump P being supported on the bottom shell l0 of the reservoir R, and the motor M being positioned above the reservoir and above the pump upon the top shell l I therer of, said shells being telescoped` and joined together as by soldering and Welding at I2. The reservoir has attached to the upper shell H by soldering or Welding the carrying strap 24, said strap having outwardly projecting holed ends 26 enabling attachment to the dashboard by the bolts 25. To the bottom of reservoir is Welded the angle 3|, the downwardly extending portion 32 oi which contacts with the dashboard and is bolted thereto through an opening 33. Upon the top of the reservoir is the filler neck 21 closed between the filling operations by the cap 28.

The iiange 36 of a support cup 31 for the motor M is secured on top of the cover immediately above the opening 34 by the studs 35 and the clamping nuts 38 screwed thereon, the lower ends oi the studs being welded at 39 to the shell The motor unit comprises a capsule 33 rigidlyv aihxed at 46 by welding, for instance, concentrically to the top of the support cupr 31' which capsule includes a diaphragm l0, which may be composed of a plurality of layers of diaphragm cloth, clamped at its rim 1| between the base element 12 and the cover element 13 of the capsule 33, the rim of the base element being folded over that of the cover element to clamp said rim 1| at 14. f

A rod 15 is rigidly aiiixed centrally of the diaphragm 'lo by a disk 1.8i and a cup. 19 disposed at opposite faces of the diaphragm and the whole being pressed through an interposed washer against shoulder 11 on the rod 15 by a. nut- 83 threaded upon the reduced upper end M of saidrod. The fish paper gasket 69 assures that there will be no leakage past the thread 8| and through the central diaphragm opening. The rod 15 extends withl Ysubstantifalf clearance through the downwardly flanged opening 82 in the motor base 'l2 and is connected to the' pump" plunger 4|? by a universal joint (see Fig. 4) comprising a hem-ispherical ball member 83 rivetedat' 84 upon the reduced upper end 68 of the plunger 4|. A coil spring 85 in a corresponding deep socket 86 at thefiower end of the rodv 15 presses'the spherical surface of the ball member 83 against a collar 6l retained in place by the inturnedlower edge 66 of the socket 26 preventing lost motion or rattling between rod 15 and plunger 4|- and permitting small misalignments between the diaphragm center and said plunger.

Suction or intake manifold vacuum is applied in operation as more fully described below through the fittings |00 and 53| Gsee Fig. 7), the former ntting being attached to the top of the cap i3 by the nut 99 and washer 96, the maximum lift being determined by contact of the rod end 3 with the lower end 98 of' the ii-tting |06 in which position the central part of the diaphragm is preferably lifted approximately to the plane of the rim il. The maximum diaphragm depression is determined by engagement of Washer 16 with base 12. Y

The diaphragm 13 is a disk of diameter greater than the internal-diameter of the capsule 33 and is suiiiciently oversize to accommodate the range of movement of its central portion, the excess diameter is taken up in a fold |0| nearA the rim 1| thereof enabling the diaphragm to be displaced through the permitted range without material strain upon the diaphragm material.

A. coil spring H32 encircling the rod 15, reacts against the fixed motor support 3T and is centered by the flange 82: at its upper end' and at its lower end againstl a centering cup 91 resting upon a nut |63 threaded upon the rod. The spring |32 is precompressed by initial adjustment of the nut |63 which nut is thereupon locked in position by mutilating the thread |64 by a blow upon a pointed tool inserted through hole |65 in the nut so that it will retain the diaphragm 1G in balance between the upper and lower limits of diaphragm movementat levels roughly proportional to the magnitude of the suction.

The pump structure P (see particularly Figs. 2 and 4), consists of a pump body |26 provided with a shoulder 2| adapted to contact in a lubricanttight fashion with the bottom of the shell l0 by means. of the gasket |22. The body has a central nipple portion |23 extending upwardly within the reservoir and centrally bored at |24 to receive the long unpacked plunger or piston 4|, the upper edge of said bore being provided with a depression |25 to enable more ready insertion of the plunger. The lower portion of bore |24 encircling the plunger |29 is enlarged to `form a lubricant receiving and discharging pump chamber |36.

The strainer unit is assembled on the sleeve |28 and comprises an annular dome-shaped metallic screen strainer member i3|, preferably drawn out of a at piece of strainer screen material, the lower end of which is closed by the plate |32. The outery rim of.' the plate |32 is clamped to the outer rim iof the strainer by the ring |88 and the inner rim ofthe plate is soldered to the shoulder |36 on the sleeve |28. The upper inner rim iii' of the strainer is clamped between the annular plates. |31 and |38 and tothe shoulder 33 by the. staking |46, the upper plate |31 extendingv outwardly to protect the strainer from i-njf\,uy.A They strainer assembly is placed upon the nipple |23y and ispressed at its lower end against the bottom ofthe tank' il) by the nut |21 screwed upon the upper threaded portion |26 of said nip.- ple, this operation also drawing the shoulder |2| of the pump body up against the reservoir bottom..

The periphery of thev bottom plate |32 of the domed strainer |3| is fixed in a lubricant-tight fashion to the bottom of the shell t8 by means of the annular cork or cork-vellumoid gasket |42. The plate |32 beingV provided with one opening |43 to permit of entrance of strained lubricant to the inlet passageways |44 and |45 and with another opening |46 to receive the doyvel pi-n |41 which nts in a socket 48 in the body |26 and serves to locate said body in respect toY the reservoir.

The lower portion of the bore |24 is further enlarged and tapped at |49 to` receive a threadedhollow plug |56 provided with a illister slot iai and interiorly formed with aseat |52 for a spring'- seated ball check i 53 enclosedv therein. The cornbined spring support and ball check retainer i541 is also enclosed within said plug |56 by staking |55' and is provided with openings |56 to permit the ready flow 0i lubricant into the chamber |30 below the plunger 4| during up stroke thereof. The plug |56 has a liquid-tight connection with the bottom of the tapped socket |49 by means or the fish paper gasket |52', the outer end of the socket being closed by the plug |58 protected against tampering by the plate |59, the chamber |66 between the plugs |50 and |58 serving as a pump inlet chamber to pass lubricant from the inlet passage to the inlet Valve |53. The body |20 is also provided with an outlet passage I6! (see Fig. 2) which leads to a tapped socket |62 containing the hollow threaded plug |63 enclosing the spring-seated ball check |64 and the seat therefor |55, the plug ntting the bottom of the socket |62 in a lubricant tight manner by means of an annular iish paper gasket |66. The plug |63 is attached to the outlet piping |61 by suitable connection to its tapped outlet socket |68. The additional bracket 3 is welded to the bottom of the reservoir and has an opening |86 therein through which the'body |20 projects. It will'be noted that both the inlet and outlet valves are' enclosed in readily removable fittings which are positioned in tapped sockets exterior of the reservoir, with the result that such valves may be readily removed, inspected and replaced.

The reservoir R is vented, preferably throughV a hole |05 in motor base 12 which communicates with the reservoir through the clearance space between the flange 82 and rod 15. Plate 18 shields the diaphragm from injury due to the possible insertion of an instrument through said hole |05. The hole |06 being at high levelwillprevent escape of oil onto thetop ofthe reservoir.

The reservoir-motor-pump unit, shown in Figs. to 4, is particularly suitable as the propulsive mechanism for feeding lubricant to a central chassis lubricating system leading to the bearings of an automobile chassis. In Fig. 5 is shown a diagrammatic arrangement of such installation. The 'reservoir R shown affixed to the dashboard D is connected with the intake manifold by means of a pipe |8| leading to the fitting 53|.

The pump outlet line |81 communicates by means of a Vjunction |68 with the main |69 extending along the side member |10 of the chassis, said main |69 communicating with a similar main |1| valong the other side of the chassis |12 by means of a cross-over |13. `The cross-over |13 is supported upon an intermediate transverse supporting member 402 at about'the middle of the chassis substantially to the rear of the reservoir R but substantially in front of the rear spring hingebolts |19. -The mains |10 and Y!1| extend the entire length of the chassis and supply with lubricant the front springv shackle bolts at |13, the knuckle .and brake operating structures at |14, the fuel pump at |15, the front spring hinge bolts at |16, the clutch release bearing at |11, the intermediate brake shaft bearings at |10, rear spring hinge bolts at |19, brake idler levers at |82 and the rear spring shackle bolts at |83. In Fig. 5 the smallV circles represent flow metering devices or drip plugs, the small rectangles |68 representjunction fittings, the small Itrapezoids |84 represent sheet metal couplings which are soldered to the connecting piping of the' conduit system and the dotted lines represent gravity feed lines beyond the drip plugs or other pressureabsorbing flow metering instrumentalities.

In advance of each of the bearing inlets, as

indicated in Fig. 5, is provided a flow metering device of any ofa variety of constructions, a preferred embodiment of which shown in Fig. 6 is of the general type disclosed in the prior Patent No. 1,632,772 or application Serial No. 155,810 filed December 20, 1926. The device of Fig. 6 has a cylindrical. or cartridge-like body ||0 preferably of aluminum or brass having `an outlet socket |53 conformed as a Valve seat 4 with a coacting nap valve ||5 retained in place byl means of a perforated and embossed retainer i |13; and an inlet socket |1 into which is plugged felt strainer |58 having a backing cup ||9 of wire mesh. in the longitudinal bore between these sockets is disposed a restriction pin |20 maintained by staking at |2| from engagement with the valve. Pins of different diameters and/cr lengths may be used in accordance with the desired ratingsfof the fittings,l the longitudinal boresl of the fittings in one desirable embodiment being identical. 1 The drip plug abuts the bottom of the tapped socket 89 at itslower edge. Y Into this socket is threaded the steel bushing 90 which encloses thev Ving or deforming the bronze comp-ressio-ncoupling sleeveA 92 against the nipple 93 inserted into said pipe end, said nipple alsol being provided with a telescoped skirt serving to clamp the felt strainer annularly. The coupling 'sleeve 92 is bottomed at its lower knurled surface upon the top of the cartridge H0. The bronze sleeve 92 being fairly hard resists deformation to a certain extent and prevents gripping of the thimble 93 by the pipe Vend 9|' with sufficient force to cause withdrawal 4of said thimble when the pipe end 9| is removed after unscrewing the coupling nut or bushing 90. rI'he lower part of the drip plug body H0 is provided with a groove 94 into which ts the snap ring 95 to prevent inverted insertion of the drip plug into the socket 89.

The system being installed on the vehicle as shown in Fig. 5 and the oil reservoir being charged, the parts remain in the relation shown in Fig.` 1 as long as the engine is' at rest, the spring |02 depressing the diaphragm to its lowermost position. During running of the vehicle, suction is applied from the intake manifold to the motor cap 13. Under such suction the central part of diaphragm 10 moves upward, drawing vwith it the pump rod 15 and the pumpr plunger vMaand stressing the spring |02. Depending on the degree of suction, which for some vehicles,` under some running conditions may be as high as |8 inches of mercury andfor other vehicles under other runningv conditions may be as low as 6 inches of mercury, the spring |02 will be'correspondingly compressed to equalize the pressure diierential onthe diaphragm and dispose the diaphragm center at corresponding level. vThus Yunder all usual operating conditions the diaphragm 10 Yfloats at a level varying sub;

stantially directly with the suction exerted by v the intake manifold.' Y

The diaphragm being in any of various floating positions set forth, when as by opening the throttle, the pressure becomes more nearly atmospheric, the spring |02 will expand and thereby depress the diaphragm 10, consequently urg ing the pump 'rod 15 downward and with it the plunger 4|, the charge in chamber |30 being discharged into the distributing pipe system. kIn this manner each material decreasein the manifold suction due to any of various frequently occurring vehicle drivingA conditions or manipulations will bring about discharge of the pump into the distributing line, the pump being discharged (and also charged) solely as a result of variations of manifold suction, regardless of the average magnitude of the suction.

The motor unit M is quite sensitive to small suction variations, for the diaphragm moves with little or no friction and the spring |02 is free from rubbing contact with other parts. On, frequent occasions in the ordinary course of vehicle operation,`the pump will perform -a full stroke, particularly where the throttle is first closed and then opened fairly wide, as in shifting gears and the like. A few ofrsuch full strokes are effective to eject into-the pipe line any residual air trapped in the pump inv initially operating or charging the reservoir, which `air will proportionately escape through the drip plugs of the distributing systernand be replaced by oil that completely fills and maintains iilled the voids in i Ul the pump as the pipe lines are preferably of such small diameter as to pass airv and lubricant.

Due to small clearance of the plunger in the elongated pump cylinder |24, leakage is substantially eliminated and .substantially the entire amount of oil displacedV by the plunger 4| is ejected past the outlet valve |64 into the distributing system. Return of oil to the reservoir past the inlet ball Valve |53 is prevented, as the spring positively and effectively seats the ball, eliminating tendencies toward leakage, which might otherwise occur, especially, when the oil .is fairly viscous as in cold weather and tends to form a lubricant film upon the seat |50 preventing perfect contact therewith by the valve.

As the small clearance between the end of plunger 4| and the inlet valve |53 is completely lled with oil, as above noted, suflicient suction is exerted even in pump strokes as short as 1% inch to eifect lifting of the valve |53 and drawing in of a lubricant charge. The relative frequence of operation of the. pump during ncrvehicle operation, especially in view of the limited resilience of the pipe system results in a more or less sustained pressure therein, to effeet a more or less continuous delivery by the drip plugs throughout vehicle operation under line pressure adapted to the Viscosity of the oil. When the oil is quite Huid, as in hot Weather, the line pressure may be as low as one pound, or less, to which pressure the flap Valves ||5 Vof the drip plugs will readily respond, while in win ter weather, the pressure may rise to fifty pounds per square inch, or more;

Delivery of lubricant through the respective drin plugs will occur at the relative rates determined thereby, the total delivery being determined by the pump. When the vehicle stops, eren though the engine be idling, lubrication ceases, any incipient leak through a bearing at low level being checked by the consequent suction of the light flap valves H5' kof drip plugs at higher level against their seats |14, the pipe system thus always remaining filled.

Wlnle the various elements. of the lubricant supply unit may be made in proportions or dimensions suited to the particular use to which the device is put, the application of the device automobile chassis lubrication renders certain dimensions and proportions peculiarly suitable for universal application to Various widely differing makes of automobiles. For such purpose the pump plunger preferably has a crosssectional area of l 50 square inch, the diaphragm has a diameter of 2@ inches and a stroke of 1A inch. The tank if of. quart size may have an overall diameter of afboutifi/,t inches and an overall depth of about 45/8 inches. In such arrangement spring 85 may be precompressed so as to be under normal .stress of say about three pounds, in which case it will transmit a pump pressure upv to 150 pounds per square inch without resilient loss. In case of obstruction to the discharge lof thel pump or the use of an excessively viscous oil when there is tendency to create excessive pump pressures in excess of three hundred pounds. beyond the limit the system safely admits of, there will be a further vcompression of the spring permitting depression of socket 06 over the plunger M, the resiliency of the spring under such conditions serving toy take up part of or the entire movement of the diaphragm and thus protecting the system.

In use of the system, as thus far described, it is apparent that, were the parts so arranged or setas to feed approximately correctly under conditions of sustained highway travel, there would be a great excess of lubricant feed under conditions of city driving, where the manifold .suctionor vacuum would be varied suddenly and frequently through wide ranges, during the recurrent gear shift and brake operations. To prevent the consequent over-lubrication under such conditions of operation, means may be preferably provided automatically to reduce the effectiveness upon the motor M of such sudden changes in suction and/0r the amount of the pump discharge. According to the embodiment of Fig. 7, a choke, throttle or damper means is preferably interposed in the path of suction applicati'on from the manifold |80 to the motor M. In this embodiment a fitting 53| generally similar to the drip plug fitting of Fig. 6 is utilized in which, however, protective felt plugs 533 are provided both in the inlet and outlet sockets 532 to protect therestricted passage from clogging. The restriction pin 535v may be inch in length and afford a radial clearance of 0.002 inch which produces a clickingl effect equivalent to that of six feet of' pipe of @la inch bore. The radial clearance may be changed by use of different sized pins to change the dampening or throttling effect of the fitting 53|. The choke plug is threaded into a socket 536 in the upper side of block |00.

Thus', inoperation whensuction is suddenly and temporarily applied at the manifolds |30, the air or gas can escape but slowly from the motor head 'I3 through the choke plug 53| so that before the pressure will have been greatly reduced in the motor, the suction in the man1- fold will again `have become less intense. Thus the variations of suction on the motor are maintained within relatively small ranges notwithstanding sudden temporary variations of suction of great magnitude at the'rnanifold.

In Fig. 8 is shown a slightly different form of throttle device T which may take the place of the fitting 53| and be inserted in the outlet socket |02 in lieu of the plug |33. This device may consist of a body |90 provided with an inlet socket |91 with an enlargement 20|, a tapped outlet socket |58 and a small bore |09, forming a connection between said sockets, the inlet side of thebody being threaded at 200 for insertion within the socket |62. Within the enlarged portion of the socket is press fitted the hollow plugs 202 and 203 telescoped together at20'l, the former 'plug havingA a seat |65 for the ball check |64', the springV 206 of which is enclosed within the smaller inlet socket |31. In the chamberV 209 between the plugs 202 and 203 is enclosed a spring seated ball 208 which may reciprocate between the seatsI 2 I0 and' 2| formed in the plugs 202y and 203 respectively. The device is protected by means of felt strainer 2 l2 backed by the screens 2| 3 and annularly retained in place by the washer 2M, the edges of the enclosing socket being staked over said washer at 2|5. The ball check |64 will act as the ball check of Fig. 2 preventing reverse flow from the system to the reservoir.

In operation the ball 208 having a very small clearance, say in the order of 0.001 to 0.004 inch, in respect to the side wall of the chamber 209, will move from its seat 2| Iat low rates or" lubricant discharge and will permit said discharge to pass into the piping system.V Upon more rapid or excessive discharge, however, the piston ball 208 will be thrown to its other seat 2|0 and will substantially check lubricant :dow from the pump into .the conduit. Y

In Fig. 9 is disclosed another embodiment o a throttle device or iiow governor T2, very similar in operation to the device of Fig. 8 V(similarly functioningparts being designated by the same numerals as in Fig. 8 provided with a superior 2). In this embodiment a cylindrical plunger 2332 which `may be conveniently-made of aluminum reciprocates between the seats 2N2 and 2132, the cylindrical plunger 2382 being normally spring pressed against seat 2i i2 and being.

displaced to cooperate with seat 2l2 upon excessive pump discharges. The plunger is provided with a spring guiding extension 333 around which is placed an annular piece of oil-silk liti, said oil-silk cooperating with the seat 2N2. The clearance between the plunger 2332 in respect to the Walls of the chamber v2332 in which it is contained may be somewhat greater than but is preferably of substantially the same order as that Yof the ball piston 208 of Fig. 8.

To enable determination of the need for refilling the reservoir a level indicating arrangement L (see Figs. l and l0) is provided.` This arrangement includes a cork float 2|5 held in position on a rod 22B between the washers 2H and 2l8, the washer 2H being xed to the rod n' by theriveting 219 and the washer 2i8 byY the staking. 22B. The rod passes upwardly and is guided in the opening 22d in the bottom ofthe sleeve 221 and the opening 222 in a plug 223 and pressed into the upper. portion of the sleeve. The sleeve 221 projects downwardly vthroughy an opening 228-in the top of the reservoir and the upper end thereof is riveted at 22S to the plate 230 which Vplate is clamped between the vel-l lumoid-cork gaskets 23! and 232 to the top of the reservoir. The gaskets and plate are retained in the bottom of the cylindrical housing 233 which is soldered or welded by the flange 234 to the top of the reservoir (see also Fig. 3). Enclosed within the housing 233 is the glass cylinder 235 which is clamped between the gaskets 23| and 233 by the cover 237 tting over the top of the housing 233. The visual indicator consistsV of a central cylindrical member 233 which is shouldered at 333 and 404 to receive the lower and upper cups 263 and 2M respectively, the upper cup being held in position by the riveting 222. Enclosed between the cups 240 and 2M is a strip of Celluloid rolled into a cylinder 243 with the continuous oblique markings Empty extending around the outside thereof (see Fig. 1);

In operation when the tank contains suicient lubricant the visual device will be forced upwardly in the part of the glass cylinder 235 above the openings 245, the elevations 405, contacting with the gasket 236. When the lubricant level becomes undesirably low, however, the, cork 2I5 will float near the bottom of the tank and will lower the visual indicator between the diametrically opposite openings 265 in the lower sideV of the cylindrical housing, whereupon the operator will readily observe that the reservoir needs relling. The visual indicator-flow combination will eitherbe stopped by the projections 405 contacting with the gasket 236 or by the projection 219 contacting withv the bottom of the tank assuring that no rupturing stresses will be applied Vto the combination. The gaskets` 23H, 232 and 236 will seal the chamber inside of the glass cylinder 235 substantially decreasing the tendency of Voil to creep upwardly thereinto fand preventing any leakage onto thetop of the tank..r

As many changes could be madeA in the above construction,and many apparently widely different embodiments of thisinvention could be devised without departing Vfrom the scope thereof, itis intended that all matter. contained in the above description or shown in the accompanying drawings'shallbeV interpreted as illustrative and not in a limiting sense.
